Deploying a NodeJS App on an AWS EC2 Instance: A Comprehensive Tutorial from Cache Cloud

In this tutorial, we will go through the steps to deploy a NodeJS application on an AWS EC2 instance. This process involves creating an EC2 instance, setting it up with NodeJS and deploying our application on it.

1. Sign in to your AWS account and navigate to the EC2 dashboard.

2. Click on ‘Launch Instance’ to create a new EC2 instance. Choose an Amazon Machine Image (AMI) that is suitable for your application, such as an Amazon Linux AMI.

3. Select an instance type that meets your requirements, and configure the instance details as required. You can choose the default settings for networking, storage and other options.

4. In the ‘Configure Security Group’ step, make sure to create a new security group with the necessary inbound rules to allow access to your application. For example, you can open ports 22 for SSH access and port 80 for HTTP access.

5. Review and launch the instance. Choose an existing key pair or create a new one to access the instance securely via SSH.

6. Once the instance is launched, note down the public IP address or DNS name of the instance to access it via SSH.

7. Connect to the instance using the SSH key pair you selected during the instance launch. Use the following command to connect to the instance:

ssh -i /path/to/your-key.pem ec2-user@public-ip-address

Replace /path/to/your-key.pem with the path to your SSH key pair file and public-ip-address with the public IP address of your instance.

1. Update the packages on the instance using the following command:

sudo yum update -y

This will ensure that the instance is up-to-date with the latest software packages.

1. Install NodeJS on the instance using the following commands:

curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -
sudo yum install -y nodejs

This will install NodeJS version 14 on the EC2 instance.

1. Verify the NodeJS installation by checking the version using the following command:

node --version

You should see the installed NodeJS version displayed in the output.

1. Clone your NodeJS application repository or copy the application files to the EC2 instance using SCP or any other file transfer method.

2. Install the application dependencies by navigating to the application directory and running the following command:

npm install

This will install all the required NodeJS modules and dependencies for your application.

1. Start the NodeJS application by running the following command:

node app.js

Replace app.js with the main file of your NodeJS application.

1. Access your NodeJS application using the public IP address or DNS name of the EC2 instance in a web browser. You should see your application up and running on the AWS EC2 instance.

2. You can optionally set up a process manager like PM2 to keep your NodeJS application running in the background and handle process management tasks.

That’s it! You have successfully deployed your NodeJS application on an AWS EC2 instance. You can now access and use your application from anywhere in the world. Remember to monitor your application’s performance and security regularly to ensure smooth operation.
